Anorexic, maybe just a little.

Ok, so I have been starving basically for a month. Not the healthiest way to lose weight, but definitely efficient. I have been eating things like cups of apple sauce as meals and working out everyday at the gym. Went to the doctor not too long ago and I have lost 15 lbs this past month! However, I have been experiencing severe constipation. I do have cheat days and I do eat very small meals at times.. So I would think I'd have to go to the bathroom sometime? I haven't been all week! I've taken laxatives to relieve some of the bloating in my belly but it hasnt budged. Does anyone know of a way I can get rid of the bloating?
